The legal dispute between Apple and the consulting firm Envirodigm has entered the appellate stage. The case, which dates back to 2020, centers on allegations that Apple misappropriated trade secrets related to an anodization process for iPhone manufacturing.

Envirodigm claims that in August 2013, it shared a proprietary anodization formula with Apple under a non-disclosure agreement. The firm alleges that Apple began using this technology in 2015, starting with the iPhone 6s, without further collaboration.

A lower court previously issued a summary judgment in favor of Apple, ruling that Envirodigm failed to sufficiently define the specific trade secrets it claimed were stolen. Apple maintains that this ruling should be upheld, citing legal precedents regarding the necessity of clear disclosure.

Envirodigm is now challenging the decision by emphasizing a breach-of-contract claim. The firm argues that this claim should be treated independently of the trade secret misappropriation allegations. They contend that Apple experimented with a specific acid ratio formula shortly after their 2013 meeting.

The future of the litigation depends on whether the appellate court accepts the argument that the breach-of-contract claim is distinct from the trade secret issue. Apple continues to argue that both claims are fundamentally linked and should be dismissed together.
